A database is analogous to a warehouse, where everything is organized on shelves. But a lack of maintenance and unnecessary items are stacked on top of the actual outcome. Reaching an actual product upon request may now take longer than expected. So, you need WordPress database optimization for better execution of commands.
WordPress, like any dynamic web application, is reliant on a database. Every action in WordPress links to the database. Either directly or indirectly: from themes to plugins and comments to posts. Let’s closely look at how to optimize the database.
Solutions to WordPress database optimization issues
Here are the solutions needed to optimize the WordPress database.
Custom database schema
The first thing done at the start of any project is to design the domain data model. The post-oriented approach of WordPress database optimization allows developers to skip the data type thinking and focus on business logic. Any custom solution based on dedicated tables and a custom model includes this step of data definition.
Clearly defined data types help in data validation and ensure that the correct types of attributes are exchanged between functions or modules. Furthermore, carefully selected data types can improve the query performance of reading and writing operations in the underlying database.
Verify database performance
It is also critical for database performance and WordPress database optimization to define indexes on specific attributes based on actual data search criteria requirements. When properly used, indexes can speed up queries, but they can also slow down DML commands (Data Manipulation Language) if there are many.
Indexes are added at any time and defined for all attributes carrying information about record identifiers and table relationships i.e. primary and foreign keys. A good option is to use composite indexes based on expected query scope, as WordPress does in its tables, to reduce the overhead of storing and managing indexes.
Handling data operations
After creating the custom schema, we can proceed to the data operations handling in PHP. WordPress database optimization provides an excellent class, wpdb, that allows developers to perform all types of SQL queries and commands on the underlying database, such as selecting proper table name prefixes, statement preparations, and data fetching by rows or columns.
Note if you want to reduce wpdb overhead, you can query the database directly using PDO or MySQL PHP extensions and their functions. Remember that you will need to handle various operations in optimizing WordPress database optimization, such as by implementing a custom wrapper class.
Use of dbDelta
There’s also a beneficial tool for keeping your custom table definitions up to date at the PHP level. It is known as dbDelta, which is available in WordPress as a function of the same name.
You can add or remove columns from existing database tables, and the plugin will automatically update based on existing and new table definitions. dbDelta handles the extraction of changes between schemas and uses DDL (Data Definition Language) commands as needed.
As you can see, any custom work centered on a database-oriented project necessitates at least a basic understanding of SQL queries and commands, ranging from table definitions (CREATE TABLE) to search queries (SELECT). Hire a WordPress developer for more technical guidance.
Advanced custom fields
ACF Custom database tables is a companion plugin for the Advanced Custom Fields plugin that allows you to store ACF groups and fields in separate tables in the database.
Each ACF group can contain various fields of diverse types. ACF saves these fields as meta entries next to posts by default, which may result in an overloaded WordPress database optimization posts meta table.
The mentioned plugin allows storage of these custom fields in separate database tables. Instead of being an independent meta record, each has its column. The plugin’s most recent version allows you to configure attribute types for any field.
It’s one thing to optimize your code stores and retrieves data. The software configuration that powers the WordPress instance, DBMS, is also critical (Database Management System).
As previously stated, WordPress makes use of MySQL (or MariaDB), a highly efficient relational database software. There are some areas where relational databases perform worse than object-oriented databases, but that is beyond the scope of this article. MySQL, like any other service, requires tuning based on its actual purpose and load.
Hire a WordPress developer for more technical guidance. There are numerous tutorials available that explain how to select appropriate values for parameters responsible for performance gain. It is worth configuring and tailoring them to actual needs and hardware capabilities.
At some point, every piece of information in the database has a value. Domain data drives business processes, logs aid in debugging, and settings allow you to customize and personalize the look and behavior of your website.
As previously stated, trashed or orphaned data may accumulate over time, in most cases, this obsolete data occupies the space of WordPress database optimization without being read by any relevant processes.
Any data model implemented in the database as custom tables are designed in a way that identifying old data is efficient and quick. Indexes speed up data search in SQL operations that use the DELETE command, so running them on specialized custom tables will take less time to execute than searching through posts.
Conclusion: To some extent, every WordPress-powered site stores and serves content from its underlying database. WordPress provides developers with intuitive post mechanics, also opening the door to database performance issues. For more consideration, consult WordPress support for your projects.
